Summary

The video explains three stages of AI tools: chatbots for one-off tasks, DIY agents that retain information in files, and personal agents that use that information proactively. DIY agents offer flexibility and control but require setting up a system, while personal agents provide a more beginner-friendly, ready-made experience and can run continuously in the cloud. The trade-offs include capability, ecosystem lock-in, and privacy; open-source tools run locally offer more privacy but can be harder to set up. The creator recommends choosing based on how much customization, convenience, and control you want, and expects AI platforms to combine these approaches over time.

Key points

Chatbots are suited to one-off tasks and generally cannot connect a new request to a broader history of information.
DIY agents can save and update information in files, then use it across future tasks.
Personal agents are presented as proactive versions of DIY agents: they can notice relevant events and offer help without being prompted.
A DIY setup can link information across folders and connected apps, such as travel preferences, contacts, calendars, and deadlines.
Personal agents provide many similar capabilities without requiring users to build and maintain their own file system.
Personal agents can monitor for changes throughout the day and run around the clock using dedicated cloud computers.
DIY agents offer more control and are described as more capable, while personal agents are newer and may create ecosystem lock-in.
Privacy is a personal trade-off; running open-source agents and models locally can offer a privacy-focused option, but setup may be intimidating and local models may be less powerful.
The creator suggests personal agents for ease of use and DIY agents for customization, capability, and platform flexibility.

Full transcript (original language)

00:00 If you already use ChatGPT, Claude, or Google Gemini, then you might be wondering what makes personal agents like Muse, Dots, and GrokBot any different. [music] I mean, the demos and the headlines are extremely impressive, as usual, but are personal agents actually worth investing your time and effort to set up? [music] In this video, I’ll explain what personal AI agents are in plain English and how they differ from tools you’re already using, so that you can judge whether personal agents are worth your time. Let’s get started.

00:30 Instead of diving straight into the deep end, let’s start with the AI tools you’re already familiar with. Kicking things off with chatbots like ChatGPT chat, Claude chat, and Gemini [music] chat. In a nutshell, this category of tools is great for one-off tasks that do not depend on information you’ve shared before. For example, let’s say you upload your latest health report to ChatGPT chat to better understand the findings. You, the user, type in a prompt with instructions and ChatGPT chat, the chatbot, gives you a summary

01:00 of that specific report in plain English. [music] That was a useful one-off task, but ChatGPT chat only received access to that one report. So, it has no way of connecting those findings to your broader health history like your past reports or your doctor’s notes. Keep that limitation in mind moving forward. Next, we have the do-it-yourself, or DIY, AI agents category, which includes apps like ChatGPT work, Codex, [music] Claude Code, and Gemini Spark. And in a nutshell, this category of apps can

01:31 remember and >> [music] >> update information you’ve previously shared. So, you don’t have to explain your situation every time you start a new task. Continuing with our health example, let’s say you first give ChatGPT work access [music] to a health folder containing your previous health reports, your doctor’s notes, and your supplement stack. Then, you share this year’s health report in a new task with the exact same instructions as before. And here’s what happens. First,

02:03 the AI saves the report in your health reports folder. Second, it compares the results with your last 5 years of reports and notes from this year’s doctor’s visits. And third, it updates your health history by editing your health memory document directly so that next year’s comparison starts with everything you shared this year. By the way, I’m using the term DIY agents in this video because unlike the personal agents we’ll cover later, we basically have to set up these folders and files from scratch. Now we arrive at the

02:34 personal agents category, which includes apps like Meta’s Muse, ChatGPT dots, and XAI’s Grok bot. And to over simplify, personal agents are just the proactive version of DIY agents. As in, they use what they know about you and offer help before you ask. Continuing again with the health example, your personal agent would message you 1 day before your annual health checkup with [music] something like, “Hey, your annual health checkup is tomorrow. Would you like a

03:04 summary of your health trends over the past 5 years to take with you?” And that’s what I mean by proactive. The agent noticed an upcoming appointment, connected it to information you’d already shared, and solved a problem for you without you having to remember to ask. That was a simple example, and it might sound like a small change, but it takes a massive weight off your mind when an always-on assistant is keeping track of things for you. At this point, it should be pretty clear why the industry as a whole is shifting away

03:36 from chatbots and one-off tasks and towards DIY agents and personal agents that know what we care about and can proactively flag issues without us having to even think about it. By the way, if you’re finding this helpful so far, my free newsletter gives you one insanely actionable AI tip every week that you can apply in under two minutes. Link down below. [music] Now, before getting to personal agents, we first need to understand how DIY agents work because the same principles apply to both. As we saw earlier, tools like

04:07 ChatGPT work, Claude Code, [music] and Gemini Spark can write down and maintain our rules, preferences, and memory in plain text files. Then read those files when a task calls for them. For example, as you can see, every single reply I get from Claude or ChatGPT work ends with a what’s next section, which drastically reduces decision fatigue for me. And that preference is saved in this one text file that governs how I want the AI to reply to me. And the AI reads it

04:40 every time I start a new task. So, to be clear, I tell the AI my preference once, it writes it down, and it follows the rule forever. Zooming out a bit, this governance rules file is just one of over a hundred plus text files in my home folder, which I call Jeff OS. And inside it, you can see all these folders, right? And every single one of these represent a different area of my life. And just to clarify, although I

05:11 literally started off with a completely empty folder, I did not have to manually create any of these. I just tell the AI what I want, and the DIY agent does the grunt work of writing, updating, and organizing the files inside my home folder. And that’s how I built more than 30 plus folders, each containing the instructions and information my AI needs for that part of my life. Now, let’s make this more concrete by going over two use cases. Starting with my friends and family folder, the memory.md file here keeps track of information like

05:43 family birthdays, food allergies, and even presents I previously bought because I’m a very petty man. >> Oh, I love it. >> Really? You’re not going to return it? >> Well, not this second. >> And then I can ask something like, “I’m planning a surprise birthday for my brother at this particular restaurant.” And the AI checks the restaurant’s menu against what it already knows about my brother, flags my brother’s severe shellfish allergy, and recommends a

06:14 different restaurant nearby with a similar price point. Heads up, this next example is a lot more complex, but [music] it’s a realistic representation of how I use DIY agents day to day. Let’s say I’m planning a trip. I literally kick things off with a simple sentence like, “Help me plan a trip to LA from May 20th to 30th.” And even though I send this off with no other context, it’s able to pull everything it needs because the agent has access to my travel folder, and it’s also connected to apps like,

06:46 here you can see, Notion, Google Calendar, Google Drive, and Gmail. And so it pulls my travel preferences to find Marriott hotels in my preferred price range, and checks the visa requirements for the passport I hold. It looks through my people database in Notion for friends and acquaintances who live in LA so I can reach out to them. And it also creates a trip project in Notion the way I like it by following my saved Notion conventions. And finally, it checks my calendar for conflicts and

07:17 flags any tasks or projects with deadlines that fall during the trip. So just to be clear, my hotel preferences, my friends’ locations, and my project deadlines all live in different places, but they all matter to the same trip. So the AI connects those details for me without me having to remember and re-explain every single one of them. Put simply, DIY agents represent the ultimate second brain, where you can offload and retrieve information you want without really having to organize

07:48 any of that yourself. By the way, if you want my exact setup, check out the Co-worker Academy and you’ll get a ready-to-install second brain that loads your contacts automatically and is 90% built the moment you download it. Link down below. All right, we’re now finally ready to talk about personal agents. In a nutshell, tools like Meta’s Muse, ChatGPT dots, and XAI’s Grok dots are the ready-out-of-the-box version of DIY agents, meaning you get a lot of the same capabilities without having to

08:18 build your own home folder first. For example, let’s say I want to get healthier, but I don’t want the hassle of creating and maintaining a health folder and having to understand what a claw.md or a memory.md file is. Like, what kind of NASA-level computer science language is that, right? In which case, I can just open up a personal agent like Muse, go into goals, pick health, [music] and have Muse interview me and come up with a plan to improve my sleep quality. In this specific example, it

08:48 asked about my calm routine and after I answered, it saved a goal under the goals tab and then, if I click in, it also created a bedtime checklist >> [music] >> to help me get started. Now, to be clear, DIY agents could have done all of that easily, but I would have had to know to ask it to interview me and [music] ask it for a bedtime routine checklist. Whereas Muse basically made that process dummy-proof. And if I open up Muse’s system files, you’ll notice

09:20 that, huh, this looks remarkably similar to the file architecture in Jeff’s [music] DIY setup. Some of the file names are even exactly the same. agent.md, memory.md, agent.md, memory.md, right? And if I open up Muse’s root memory.md file, you will see the bedtime routine I shared with Muse when it was interviewing me about my health goals. Put simply, both setups work the same way. The AI saves your information in files and uses those files to help you. Personal agents just

09:51 make it much easier to get started. And remember how every reply in my DIY setup ends with a what’s next section? The reason Muse follows the exact same reply format already is because I I told it in a previous chat session. As you can see here, scroll down here a little bit, I told it that every reply must end with a what’s next section listing only my remaining actions and keep it self-contained. And if I open up the memory MD file again,

10:23 you will see the reply rules are right over here. At this point, personal agents might just sound like a more beginner-friendly version of DIY agents, but there’s one more massive difference. Personal agents are proactive, meaning they can keep an eye on things that matter to you and bring you updates without you having to explicitly ask for it. For example, if you’re job hunting, you can tell your personal agent what kind of role you want and your preferred location. Then ask it to keep an eye out for matching opportunities. Or if you

10:55 run a business, you could tell your personal agent to flag overdue invoices so that you’re not missing payments from your customers. Now, you might be thinking, couldn’t I just create a scheduled task for that? And the answer is, sure. You could easily set up a task to search for jobs every morning and send you the matches. But imagine your dream job gets posted that afternoon and applications closed before the next scheduled task can run, which isn’t too far-fetched nowadays, probably. Meaning that once a day tasks would miss that

11:26 opening completely. In contrast, a personal agent would check throughout the day and notify you of new openings as they appear. Another great use case is to ask a personal agent to flag a software subscription before it renews, or watch for a price drop on something you’re already planning to buy. All this brings up another question. When your laptop is closed, how can the agent continue doing all that work? And the answer is both simple and mind-blowing because all these agents have their own dedicated computers in the cloud,

11:57 letting them work autonomously around the clock. And so if personal agents give you all of this out of the box, why would anyone still bother with a DIY setup? Well, first, personal agents are still relatively new and immature, so they’re a lot less capable. Second, DIY agents give you complete control over how you want your workspace organized, whereas personal agents force everyone to follow one standardized system. And third, you run the risk of being locked into one ecosystem. As in, the more a personal agent knows about you, the

12:29 harder it will be to switch to another one. Now it’s time to talk about the elephant in the room, privacy. This is going to piss some of you off, but I’m going to die on this hill. >> [music] >> My stance on privacy is that it’s strictly a personal preference. Some people refuse to use any Google products, so if you’re watching this on YouTube, you’re already accepting a trade-off that many hardcore privacy enthusiasts would never agree to. I’m personally wary of Meta’s products, especially after the Cambridge Analytica scandal, which I feel like everyone just forgot about. And I even received this massive payout from a Facebook lawsuit.

13:01 And I know what some of you will say, “Jeff, why are you still working when you can clearly just retire at this point from this payout?” I mean, what can I say? Just love of the game, I guess. Technically speaking, Meta says they’ve built Muse in such a secure way that even Meta themselves can’t access your data, but I’m using Muse as if everything I write is sent straight to Zuckerberg’s personal inbox. Now, if If want a privacy-focused personal agent, [music] you’re going to need to use open-source tools like OpenClaw and Hermes and then run them

13:32 locally on your computer with open-source models. But again, there’s a trade-off. They can be very intimidating to set up and there’s no way to run the most powerful AI models locally. As a quick recap, chatbots are becoming obsolete as we move towards agents that can remember our preferences and can proactively get stuff done. These agents come in two forms. First, DIY agents like ChatGPT Work, Cloud Code, and Gemini Spark. And second, personal agents like Meta’s Muse, [music] ChatGPT dots, and xAI’s

14:04 Rockbot. So, which setup should you choose? Go with a personal agent like Muse if you want the most beginner-friendly experience without building your own system. Just keep in mind the risk of being locked into that one ecosystem. By the way, I probably should have said this way earlier. Let me know if you want a whole tutorial on Muse or dots. Go with a DIY agent if one, you want the most powerful capabilities, two, you enjoy tailoring a system around how you work, and [snorts] three, you don’t want to be locked into one [music] platform. Remember, my Jeff

14:34 OS home folder is just a bunch of folders and text files. So, I could use this in closed-source DIY agents like Cloud Code, ChatGPT Work, and Gemini Spark or open-source DIY agents like Hermes and OpenClaw. Also, I fully expect all the AI frontier labs to build personal agents into their respective DIY agents. I mean, just look at how OpenAI added dots to ChatGPT Work/Codex, [music] right? So, I feel like over the long term, we’re going to get the benefits of

15:05 both without having to move to a completely new platform like Muse. If you enjoyed this, you might want to check out how I’ve taught my AI to manage all my files autonomously. See you on the next video in the meantime. Have a great one.
